Abstract :
By the reformulation of image mapping as a problem in the mechanics of deformable bodies, image mapping is transformed into a process of finite-element analysis. A class of deformable models is developed based on the physical properties of elastic objects is presented. A force field is derived from the boundary information of the image. This force field is used to deform the elastic model so that the model closely matches the boundary in the image. Characteristics of the image data and difficulties in its modeling are examined. Compensating matching strategies, each corresponding to an elastic model, are developed
